The water in the kitchen is very slow recently. Before calling the property manager to do it, he just took a pump and pumped it in the pool a few times. What is this?

That should be the poor water in your house.

It is suggested to boil a pot of boiling water to flush the water first, so that if your home is flooded because of oil stains, it can remove a lot.

If you can't do it again, tear down the trap at home (it is detachable for the trap) and clean up the dirty things inside.

In short, it is to find a way to clear the water. The current is not smooth. There are dirty things in it, so the water is naturally blocked.

In addition, there is a special situation that the water in the pool is very slow, that is, if your floor is low, your house upstairs or other places with higher water level than your house will be blocked, which indirectly leads to your house being unable to get under the water.
